Patient's question:
Patient Age: 21Detailed Condition and Purpose of Consultation: I saw in a book that the man has a small amount of pre-ejaculate fluid leakage during erection. Will this cause pregnancy? I'm very worried! First Follow-up Question: There was sexual intercourse, but withdrawal method was used!
Doctor's answer:
Hello:Fertilization is a complex physiological process that requires the following conditions: the ovary must release normal eggs, the semen must contain normally active sperm, the egg and sperm must meet in the fallopian tubes and combine to form a zygote, which is then transported into the uterine cavity; the endometrium must be suitable for the zygote to implant. If any of these conditions are abnormal, fertilization can be hindered, leading to infertility.
Modern reproductive medicine has clarified that sperm from the male travels through the female vagina and uterus to reach the ampulla of the fallopian tube, where it meets the egg from the female ovary, which has traveled through the fimbriae of the fallopian tube. The sperm and egg combine to form a zygote, which then continuously divides and travels through the fallopian tube to the uterus, where it implants in the endometrium. Here, it continues to differentiate and develop into a fetus.
